Exposure of Sensitive Information to an Unauthorized Actor
The do_gameinfo function in BomberClone 0.11.6 and earlier, and possibly other functions, does not reset the packet data size, which causes the send_pkg function (packets.c) to use this data size when sending a reply, and allows remote attackers to read portions of server memory.
CWE-200 - Information Exposure
An information exposure vulnerability is categorized as an information flow (IF) weakness, which can potentially allow unauthorized access to otherwise classified information in the application, such as confidential personal information (demographics, financials, health records, etc.), business secrets, and the application's internal environment.
